Abstract:

【Objective】 To clarify the effects of sublethal doses of sulfoxaflor, thiacloprid and clothianidin on the reproductive development of Aphis gossypii and Acyrthosiphon gossypii in Alar cotton zone. 【Methods】 The virulence of three insecticide to Aphis gossypii and Acyrthosiphon gossypii adults were determined by leaf dipping method. The F0 generations of Aphis gossypii and Acyrthosiphon gossypii were treated with LC10 and LC30. Life parameters such as longevity, fecundity and developmental duration of F0 and F1 generations were recorded, and the life table of population was established. 【Results】 Sublethal doses of sulfoxaflor, thiacloprid and clothianidin (LC30) significantly inhibited the longevity and fecundity of Aphis gossypii and Acyrthosiphon gossypii, their longevity decreased by 27.99%-40.09% and 35.65%-50.79%, 28.19%-37.67% and 32.76%-40.27%, respectively; and their fecundity decreased by 45.01%-50.17% and 50.25%-52.24%, 21.54%-28.24% and 44.57% and 54.97%, respectively. In addition to that, the decline of Aphis gossypii was greater than that of Acyrthosiphon gossypii. The analysis of life table parameters showed that the net reproductive rate, mean generation and time of double population of Aphis gossypii and Acyrthosiphon gossypii were decreased or shortened, and the intrinsic increase rate and finite increase rate increased with the increase of sublethal dose of sulfoxaflor, thiacloprid and clothianidin. 【Conclusion】 Sublethal doses of sulfoxaflor, thiacloprid and clothianidin can significantly inhibit the longevity and fecundity of the F0and F1 generations of Aphis gossypii and Acyrthosiphon gossypii in Alar cotton zone, and the three insecticides had stronger inhibitory effect on Aphis gossypii than on Acyrthosiphon gossypii.

摘要:

【目的】研究氟啶虫胺腈、噻虫啉和噻虫胺亚致死剂量对新疆阿拉尔棉区棉蚜和棉长管蚜生长与繁殖的影响。【方法】采用浸叶法,测定棉蚜和棉长管蚜成虫毒力,以3种药剂LC10和LC30处理F0代棉蚜和棉长管蚜,记录F0代及F1代蚜虫的寿命、产蚜量和发育历期等生命参数,建立种群生命表。【结果】氟啶虫胺腈、噻虫啉和噻虫胺亚致死剂量处理(LC30)显著抑制了棉蚜和棉长管蚜的寿命和产蚜量,寿命分别下降27.99%~40.09%和35.65%~50.79%、28.19%~37.67%和32.76%~40.27%,产蚜量分别下降45.01%~50.17%和50.25%~52.24%、21.54%~28.24%和44.57%~54.97%,且棉长管蚜的下降幅度大于棉蚜。经氟啶虫胺腈、噻虫啉和噻虫胺处理后,随各药剂亚致死剂量增加,棉蚜和棉长管蚜生命表参数净增殖率、平均世代历期和种群加倍时间降低或缩短,内禀增长率和周限增长率增高。【结论】氟啶虫胺腈、噻虫啉和噻虫胺亚致死剂量能够显著抑制F0及F1代蚜虫的寿命和繁殖力,且3种杀虫剂对棉长管蚜的抑制作用大于棉蚜。
